'Twilight's' Kristen Stewart 'not allowed to grope' Dakota Fanning

"Twilight: Eclipse" star
Kristen Stewart shares a tender kiss with her friend
Dakota Fanning in their new film, "The Runaways."

Kristen plays
Joan Jett and Dakota plays her Runaways band mate,
Cherie Currie. But Joan told the Dish Rag this week that if
the love scene had been accurate, the movie would have needed a stricter rating than just an R.
